In order to increase the productivity of electrical parts, manufacturing processes using progressive dies have been widely used in the industry. With a progressive die, however, closed die forging is impossible because the part has to be connected with a strip layout so that there might arise various problems in the die design. For the proper design of a process, a prediction of the process is required to obtain relevant design parameters. In this work, three-dimensional rigid-plastic finite element analysis is carried out to simulate a precision forging process. The forging process of the stem, a part of a photo pickup hologram device, is simulated with two types of processes-open die forging and semiclosed die forging. From the results of analyses, the forging processes can be predicted successfully, which enables the die and the process to be designed appropriately.
